Breakthrough Photography X4-CPL-58MM overview

  • 1Description

The 58mm X4 Circular Polarizer Filter from Breakthrough Photography helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges and filters this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage.

A circular polarizer only differs from a linear polarizer in that it contains a quarter wave plane in addition to the linear polarizing filter. The addition of this quarter wave plane is to circularly polarize the linearly polarized light for the use of auto focus and exposure functions. Due to how the light is broken down and filtered with a linear polarizer, auto focus and exposure accuracy become skewed during use. When the light becomes circularly polarized, it permits the use of these functions.

To prevent internal ghosting and reflections while providing 99.8% polarizing efficiency, each glass surface features eight layers of anti-reflection coatings. These Multi-Resistant Coatings (MRCs) also increase the durability of the filter and help it to stay clean for longer than uncoated filters. A nano coating provides an additional ninth layer over the MRCs, resulting in an improved beading effect when in contact with water for greater cleaning efficiency.

This X4 circular polarizer filter is constructed from Schott B270 glass for increased optical clarity as well as color fidelity and features a thin, brass filter ring to minimize the potential for vignetting while enhancing durability and preventing jamming.

Helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface.
Polarizing filters arrange, and filter, directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of the light.
Clears up haze in distant landscapes and provides more saturated, vivid colors.
Strongest effect when used at a 90° angle from the sun.
Circular polarizers are ideal for use with digital cameras and autofocus lenses where a linear polarizer will often disrupt auto exposure and focus features.
2x filter factor reduces exposure by 1 stop.
Constructed from Schott B270 glass for optical clarity.
Multi-coated to prevent internal ghosting and reflections while providing 99.8% polarizing efficiency.
Nano coating provides an improved beading effect with water for more efficient cleaning.
Weather-sealed filter reduces dust, moisture, and scratches from reaching lens elements.
Thin brass filter ring helps to prevent vignetting and jamming and provides additional strength.
Filter ring can be rotated to adjust the intensity of the polarization effect.
Side knurlings to provide a more textured grip when adjusting polarization effect as well as mounting onto or removing from a lens.
58mm front filter threads allow for use with other filters.
Microfiber cloth for cleaning and maintenance.

    Breakthrough Photography X4-CPL-58MM reviews

    58mm X4 Brass Circular Polarizer Filter is rated 4.1 out of 5 by 11.
    Rated 2 out of 5 by from Filters always gets stuck Optically the filter is great although even on cameras like my D850 and Hasselblad digital back I am not really seeing a huge difference between this filter and a good B&W one. The biggest difference is the appalling outcome of how often this filter gets stuck on lenses with front diameters that are even a tiny bit larger than the filter is self. There simply is no way to grip the filter because the knurling is really tiny compared to the part that rotates. In my 30+ year career I have never seen a polarizing filter designed this bad in regards to how it physically’s a nightmare. Right in the middle of a paid ad shoot today I had to send an assistant back to my house some 22 miles away to get a filter wrench so I am totally fed up with it and will literally give it away. Skip this one, it needs to be re-designed.

    Rated 2 out of 5 by from Doesn't allow for lens hood This looked like a good CPL, but I had o return it because it doesn't allow for attachment of the lens hood on a Sony 100-400 GM that has a CPL window. Will have to try another brand. The ridges on the filter would make for nice movement, but are too wide.

    Rated 5 out of 5 by from Excellent CPL This is an exceptional product from materials, construction and performance. The rotating mechanism is the smoothest of any I own including Hoya, B&W, KLM, Heliopan, etc.� The additional gripping serrations are very helpful.� �The filter is free of distortions, and is color accurate.

    Rated 1 out of 5 by from I received a defective and broken product I ordered� the breakthrough 95mm x4 brass CPL and� what I received was a mangled item....completely shattered beyond being useful...this is not acceptable and� the picture below will give you an idea of what I am taking about. I am sure this product was not manufactured this was but unfortunately I am the one receiving a useless's useless and thus I am giving a one star. Will revisit this review when I am able to receive and use a non-malfunctioning product.

    Rated 5 out of 5 by from Worth the investment Go to the their website and read what they offer. The hype is true and I love using this product in the field. I have used several other major brands and used to spend a lot of time removing them when not absolutely necessary. Breakthrough is a product I love to have on my expensive glass and gives me image color I am looking for.

    Rated 5 out of 5 by from Favorite CPL to date So I have tried a lot of CPL's. Even the Lee 100mm system CPL. This is better. The big notches to help rotate are fantastic. I leave this on all the time. The range that the cpl works looks to be a bit wider however you will still get that X darkening like all the others.

    Rated 5 out of 5 by from Awesome filter. This is my second one breakthrough filter. Bought them for fast convenience. Lots time I perfer the Hiltech Firecrest Ultras when I have time to just play with filters. The screen ons just make it easier to carry around.

    Rated 5 out of 5 by from A fine piece of glass.. This little filter is nothing but quality through and through. Great build, schott glass, knurled edge, made in the USA, and the photographs through the filter are pin sharp..!
